the correct answer is "the rhythm and rhyme scheme add to an eerie and suspenseful tone". poetry is literature written in stanzas and lines that use rhythm to express feelings and ideas. poets will pay particular attention to the length, placement, and grouping of lines and stanzas. this is called form. lines or whole stanzas can be rearranged in order to create a specific effect on the reader.
